'AUTOMOBILE SIGNAL.

Appiicaaon mea May 27, i921. Isemina. 473,200.

This invention relates toan automobilev signaling device. More particularly it comprises means associated with the brake pedal of lan automobile which gives an indi-cation as to the slowing down or stopping of the vehicle whenever the brake pedal is brought 'into use. y i The object of the invention is to improve automobile signaling devices and to provide a simple inexpensive device of this character so that the driver of a machine may not be put to the personal inconvenience and discomfort of having to give signals manually whenever he slows'down or changes thefdirection of lhis car. Other objects of my invention will appear in the course of thel following description, wherein many unique and novel features of construction are utilized in the apparatus I have devised for accomplishing the main object of my invention. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims. y l

,The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention lmay be used.

In'the preferred form of my construction,

as illustrated in Figs. lto '7,"inclusive, I: employ a signal casing,1, preferablyrfof stamped sheet metalv andof conical shape, adapted, at its'smaller end, 2,'to be seated in the lens holding rim of a tail lamp, 3, in place of the lens usuallyv .employed therein and held in position by meansof a split wire ring 10. larger end is provided with a lens, 4c,l preferably combining a number of structural fea'- This conical casing at its.

tures designed tosimplify the manufacture e and assembling and increasethe elliciency of the device. Upon theV inner face of the lens is provided an integral hub member, 5, in a central'position-,adapted to receive thereover a light rotatable centrally aperA tured disk, 6, held seated thereon by means of a Split wir@ ring, 19, fitting L groove, 20,

on said hub. Said disk is adapted to cover'- and uncovera series of radial transparent portions, v7, provided on the lens. On its outer face, in axial alignment with the hub,I

the lens-is centrally provided with a smally l lens portion, 8, intended to serve as the usual tail light bulls-eye for the automobile. Radially arranged Vabout this b-ulls-eye are a series of alternate opaque, 9, and transparvradial sections ofthe cover disk, 6, may be transparent like the corresponding portions of the lens, but l preferably malie them of translucent material such as sheet Celluloid.

Upon each of such translucent sections on the upper half of the signal lens, I place a single letter of the Word Stopl (see Fig. 3) so that When the cover disk is rotated an appropriate distance, such Word' will'be plainly visible v.to parties Whom it is desired to inform of a change of speed or direction ofv the vehicle. p ,l may employ only four transparent radial sections on the signal and also may place the several letters of the Word ,Stop upon the horizontally opposite sections only. The signal lens, in addition to thevcentral hub, carries on its rearward face afprojecting` lug, 12, formed integrally thereon too-ne side of the hub, said lug engaging through anelongated slot, 13,. in thevcover disk and having the function, inconjunction with said slot, ofregfulatingthe amount of'motion of said disl'z.

The cover disk is also provided with aV rearwardly projecting lug, 14,. suitably attached' thereto adaptedv to .beV engaged by the free end of aV spring, l5, the other. end, 16, of which is Ypivetall'y secured tothe side of the casing. .The operating member hereinafter described Yis connected with this spring and servesr to maintain the disk in signal obscuringV position. An insulated? contact fin-ger, I7, projects into the path of the spring last referredv to and is adapted to close the electricv'circuit of a pilot-light, 1-8, preferably located onthe instrument board of the automobile, Whenever the disk is rotated and' said spring. is flexed, the other end of said circuit being connected With the spring orgrounded upon the casing. adjacent tothe Vpivot anchorage for said spring member. i

. In the preferred' form of my construction, a flexible member, 21, is vattached to the spring member near its pivoted endV and entends rearwardly through a tubular support,

22, extending Within a cylindrical casing, 23, supportedl upon av frame member, 24, of the automobile adjacent theposlti'on at which' the signal isv placed. Asshovvnin Figs. 1 and 6, I preferably attach the cylindrical casing, 23, to the frame member, 24, by.

means of a hook, 25, secured to the cap 26, of said casing. The heck Vis adapted to be engaged through a hole, 2?, provided insaidv Vframe member andthe spring tension upon" veinting Wire, 21.

the operating member hereinafter referred to, serves to properly position the casing beneath thecar. The flexible Wire operating member, 21, is connected at one end to a plunger, 31, slidably engaged Within said cylindrical casing and limited in its outward movement by the end of the tubular support Within the casing. It is moved to- Wa-rd a central pos-ition therein. by means of a coiled spring, 32, surrounding the Wire acent said plunger and' seated" against the head thereof, and' bearing at its other end, against the inner face of the perforated screw cap, 26, Which closes the endV of the casing. Y

rlfhe tubular support, 22, at one' end, is provided With a collar Which is engaged Within the cap 26, onthe cylindrical casingv 23,r

and at ,its other end enters the signal casing' 'i adjacent thepivot point of the disk-operating spring 15, extends Withnv said casing Va sutiicient distance to serve Yas an abutment to entends per end' thereof is connected to the coverk disk operating spring, 15, by means ofa fastening element 33, having' a shoulder, 34, which co-operates With` the projecting end of the tubular support, 22, toV limit the outward range of movement of the signal op- 'f't second plunger, 41, is placed Within said' cylindrical casing, 23', and is normally held in Contact with the' first mentioned' plunger, 31, by means of a coil spring,"l2,surrounding the flexible operating member, 43, and positionedv between said plunger, 41, and the inner V.fa-ce, 44 of the vopposite apertured end ofthe casing. member, 453, is secured at onev end of the plunger, 41,. and. extends forwardly through said apertures in the front end of .the cass' ing to a suitable connection with the brake rod. of the automobile.V This. connection isy illustrated in detail in Fig. 7, and comprises a two-part clip, 45, designed'to be bolted together and having a central 'enlargement so as. to. exert a pull; against the hook, 25,1l

on the cylindrical casing and hold the `latter in horizontal position beneath the body' of the automobile.`

In the modified formof my construction a signal casing of the same character as that illustrated in my preferred form.' of construction is employed,the operating means comprising a Bourdontube, 51, which has The flexible operating @ne of the clip members has an exten-V' Huid connection with a-luid Vreservoir, 152,'

position by means of a support, 53, the ends of which arefbent'in opposite directions, theV lower end, 54, being suitably shaped for fattachinent tothe frameof the automobile and thexupperend, 55,` beingV provided with va pivot'element, 56, for holding the operating lever, 57, for vthe reservoir. This support is preferably constructed'ef vtwo metal plates,

58, 59, bolted 'together and suitably 'shapedj at an intermediatepoint to encloseand se-I curely support the connecting vduct, 6l, of the oil reservoir. Theoperatin'g-lever'of this modified form of my constructionjis bent outwardly, at litsfree end, 62", andrhas attached thereto a'spring element, 63, connected with the brake rod of the automobile.y Thile I have described my signal as an attachment for a tail lamp, I do not wish to limit the invention to an attachment of this character, as in the case of the installation of my apparatus upon new cars, it will b e unnecessary to make use of the ordinary tail light, as I may easily provide as a single apparatus a signal member originally constructed to embody a casing having the usual tail lamp and the features of my invention. In order to provide for the automatic maintenance of the signal indication, I provide a latch, lever 71, pivoted to the floor board yof the automobile adjacent the brake pedal 7 2, by means of a suitable support, 3. The brake pedal is provided on one side with a beveled lug, 74, having a shoulder over which the nose of the latch engages..l A spring, 7 5, is attached to an arm on the pivot rod, 77, upon which the latch lever is rigidly mounted. The lower end of the latch lever is bent at right angles and Vprovided with a pedal, 78, positioned adjacent the accelerator pedal, 79, of the automobile, so as to be operable simultaneously therewith.

From the above description the operation of my device will be clearly apparent. Each time the driver of the automobile presses the brake `pedal and moves the same a short distance forward the cover disk of the signaling device will be rotated so as to bring transparent or translucent radial portions thereof in alignment with transparent radial portions of the lens of my signaling device and when used at night will disclose the bright radial beams of the signal lamp, certain of said vbeams bringing into sharp illumination the letters S TO P formed on the inner portion of said glass or upon the transparent or translucent portions of the cover disk. The signal will then remain in operative position being held bythelatch lever. When the turn of the corner is completed and the accelerator kpedal is pressed,

the vlatch jl'ever, vunlessI especially avoided-,- will also be touched by the foot otthe op',y
